ICP-MS (Inductively Coupled Plasma Mass Spectrometry)

Your go-to technique for ultra-trace metal analysis! Used in testing water, food, soil , cosmetics & more! 🌍💧🌿 ⚗️ How It Works: 1️⃣ The sample is converted into an aerosol and introduced into a high-temperature plasma (6000–10,000 K). 2️⃣ In the plasma, the elements are ionized. 3️⃣ These ions are then separated based on their mass-to-charge ratio using a mass spectrometer. 4️⃣ Finally, a detector quantifies each element with extreme precision (as low as parts per trillion!). ✅ Applications: Heavy metals in food 🍲 Water quality testing 💧 Environmental monitoring 🌱 Pharma and cosmetics 🧴 📌 High sensitivity | Fast results | Multi-element detection #ICPMS #MassSpectrometry #LabTesting #ElementalAnalysis #FoodSafety #WaterTesting #AnalyticalChemistry #ScienceReels #NABL #TraceAnalys

Gram Staining | Microbiology 🔬 | fundamental microbiology technique

Discover how bacteria reveal their identity through color! 🎨✨ Gram staining is a fundamental microbiology technique used to classify bacteria as Gram-positive (🟣 purple) or Gram-negative (🔴 pink) based on their cell wall structure. 🔍 Procedure: 1️⃣ Prepare and heat-fix the smear 2️⃣ Add crystal violet (1 min) – rinse 3️⃣ Add iodine (1 min) – rinse 4️⃣ Decolorize with alcohol (few sec) – rinse 5️⃣ Counterstain with safranin (1 min) – rinse & dry 6️⃣ View under microscope 🧪🔬 ✅ Gram +: Thick peptidoglycan, retains crystal violet → Purple ✅ Gram -: Thin wall, loses violet, takes safranin → Pink #Microbiology #GramStaining #ScienceLab #Microscopy #Bacteria

Synthetic Food Dyes Analysis by HPLC

🔬 High-Performance Liquid Chromatography (HPLC) is a powerful technique used to separate and quantify synthetic dyes in food samples. 🧪 Brief Procedure: 💧 Sample Prep: Food sample is homogenized and extracted using water or a suitable solvent. 🧂 Filtration: The extract is filtered to remove particulates. 💉 Injection: A small volume is injected into the HPLC system. ⚗️ Separation: The dyes are separated on a C18 column using a gradient mobile phase. 📊 Detection: Dyes are detected using UV-Vis at specific wavelengths. ✅ Used in quality control to ensure dye levels comply with food safety standards.

Methacrylate Content Analysis in Polymers Using HPLC #sciencereels

Methacrylate Content Analysis in Polymers Using HPLC High-Performance Liquid Chromatography (HPLC) is a reliable technique used to quantify methacrylate monomers in polymer samples, ensuring product quality, safety, and consistency. Procedure : Sample Preparation: Dissolve the polymer in a suitable solvent (e.g., acetonitrile or methanol). Filtration: Filter the solution to remove any undissolved particles. Injection: Inject a measured volume into the HPLC system. Separation: Methacrylate components are separated using a C18 column with an appropriate mobile phase (e.g., water:acetonitrile). Detection: Detect and quantify using UV detection at around 210–220 nm. Commonly used in material quality control, biomedical polymer validation, and dental resin analysis. #HPLC #Methacrylate #PolymerAnalysis #tamilnadutesthouse #MaterialScience #Chromatography #AnalyticalChemistry #LabTechniques #ScientificResearch

Pour Plate Method part 1 | Microbiology Technique

The pour plate method is a microbiological technique used to isolate and count viable microorganisms in a sample. 🔬 Procedure: 1️⃣ Prepare sterile Petri dishes. 2️⃣ Pour melted, cooled agar (45°C) into each dish. 3️⃣ Add 1 mL of diluted microbial sample. 4️⃣ Gently swirl to mix evenly. 5️⃣ Let it solidify, then incubate at 37°C for 24-48 hours. 6️⃣ Count colonies formed within and on the surface of the agar. ✅ Ideal for enumerating bacteria in food, water, and clinical samples. #Microbiology #PourPlate #LabTechniques #BacteriaCulture #ScienceReels #AgarPlate #MicrobialTesting #trending #viralreels See less
